Mossadeq, the orator, is difficult to judge as a politician because of the perpetual contradictions between his words and his acts, and because of his sudden changes of mood from elation to depression before one's very eyes. His absolute certainty, violently expressed in hysterical speeches, would turn to tears and sobbing. He had frequent "diplomatic" illensses and he played out macabre comedies in which he would exclaim: "I am a-dying..." and so forth. He has been compared to Robespierre, to Renzi and even to characters from the Commedia dell' Arte.
